I am short (5"1') so some tunic tops for me become cute short dresses. I will add a fitted/legging/short for jsut in case.
T-shirt dresses are my go-to summer outfit. basically, it is a cotton t-shirt, jsut really long, to the knees, or a bit below.
I add a flowy scarf, or a scarf vesty jacket, or a nice pin or statement necklace, and I am good to go.
I make sure my shoes are "nice" and carry a nice purse, and dangly earrings a fun bracelet can add to the look.
Once I am home again, all the extra stuff comes off, and it looks like I am ready for bed.
There is one black t-shirt dress dress (has a tie at the neck, jsut decorative) that a friend brought me in the hospital after gallbladder surgery in 1998. I still have it, and still get compliments!
All it is is a super long crew neck t-shirt that goes to my ankles, with slits up the calves. I add scarves, or nothing.
it is basically indestructible.http://www.headtotoeclothing.com/clothing/liliana-sustainable-long-t-shirt-dress
This is kind of what I live in for summer.
I have several colors, even prints and stripes.
